From following clearly visible, on the first carcass bed course 3a, form the second carcass bed course 3b by 15,16 of elongated sections that cover third and fourth series that can obtain from described continuous band-shaped 2a.

From Fig. 2 as seen, preparing continuous strap-like member 2a relates to one or more wire parts 17 of supplying with from each rod 17a substantially and is preferably 3-10 wire part 17 and should pass through one first extruder 18, extruder 18 links to each other with one first extrusion equipment 19, and extrusion equipment 19 is finished elasticity of supply raw material by extruder itself.

Should be noted that, for the present invention is described, the part of " extruder " expression extrusion equipment, and in this field, represent by term " extrusion head ", extruder is provided with one so-called " mould ", and the product of work passes through mould in the outlet of a correspondence that forms and make according to the given geometry of product itself and size characteristic.

Elastomeric material and wire part 17 link together in extruder 18 closely, thereby produce continuous strap-like member 2a in its outlet, and strap-like member forms wire part adding thickness wherein itself by one deck elastomeric material at least.

As required, wire part 17 can not be directed in extruder 18 and can be integrally formed in the elastomeric layer 19, and be formed in one face or two-sided on.

Each wire part 17 can comprise that for example one preferably has the fabric rope of diameter between 0.6mm and 1.2mm, or one preferably has the mfg. metal cord of diameter between 0.3mm and 2.7mm.

Advantageously, if desired, wire part 17 can be arranged among the continuous strap-like member 2a, make the carcass bed course 3 that so obtains have outstanding compactedness and uniformity, for this reason, wire part 17 can for example be arranged near the density of circumferentially measuring on the carcass bed course 3 of the equatorial plane X-X of tire 1 greater than 6 wire parts/centimetre.In any case best wire part 17 should be arranged so that in strap-like member 2a that the phase mutual edge distance between the center is not less than 1.5 times of the own diameter of wire part, can carry out suitable gluing operation like this between each adjacent line.

Continuous band-shaped the 2a that comes out from extruder 18 can be advantageously by one first collector and compensator device 19a and guide at an overlay device, its structure and operating characteristics are described in detail in the applicant's european patent application No.97830731.2, and its content at this as a reference.This overlay device is suitable for continuous strap-like member 2a is cut into the

section

13,14,15,16 with predetermined length continuously.

At each

section

13,14,15 of cutting, immediately it is covered on the annular brace 11 after 16, make section have a U-shaped configuration of profile in the environment of annular brace itself, like this at section 13, can have two sidepiece 13a in 14,15,16,14a, 15a, 16a, these sidepieces radially extend to the axis of annular brace 11 in the position of axial each interval, and a top 13b, 14b, 15b, 16b extend a radially outer position between sidepiece itself.

Annular brace 11 can be by driving and the rotation of tilting with the synchronous motion step by step of the operation of described overlay device, makes each

section

13,14 like this, 15,16 dissection follow its with the section of placing before 13,14,15,16 circumferential isolated locational coverings.

In more detail, the rotation of annular brace 11 is carried out with an angular pitch, and a circumferential displacement corresponding to this pitch equals the twice of a plurality of width or the described at least width of each

section

13,14,15,16.

Should be noted that for purpose of the present invention, when not indicating in addition, term " circumferential " expression is arranged in equatorial plane X-X and near a circumference of the outer surface of annular brace 11.

Because the aforesaid operations order is carried out the covering of the banded section 13 of first series around its axis rotation for the first time fully according to annular brace 11, described section circumferentially distributes at the circular pitch that equals each section double-width.Therefore, clearly visible from Fig. 4, form a space " S " belonging between one of first series and another section, this space has the width identical with section at least on the 13b of the top of section itself.

According to the present invention, as can be seen advantageously, unlike the prior art, the covering of each section can not occur in the meridian plane of annular brace 11, promptly passes through a plane of the geometrical axis " O " of annular brace itself.Clearly visible from Fig. 8-10, on the contrary, the covering among the first overlay planes N with respect to described meridian plane P Parallel offset of each section 13 that belongs to first series carried out.

For specification of the present invention, " Parallel offset " be illustrated among Fig. 8-10 overlay planes N when from a direction that is parallel to annular brace 11 geometrical axis " O ", looking be basically parallel to the meridian plane P or at least under the line the infall of plane X-X and geometrical axis always can not converge with the geometrical axis of annular brace itself.Work as the Shi Buhui that from become a direction radially with geometrical axis " O ", looks like this and prevent that the overlay planes of each section from also favouring the meridian plane, make the top have a gradient that direction is required with respect to parallel geometrical axis itself.

But in a preferred embodiment, the first overlay planes N is parallel to the meridian plane P, even this means when still parallel when looking with respect to a radial direction of geometrical axis " O ".Like this, carry out the covering of each section 13, make its top 13b and more specifically each is arranged on wire part in the described top and is arranged in a plane that becomes with geometrical axis " O " radially substantially, thereby each sidepiece 13a extends in the direction that becomes reference planes R inclination given angle " α " radially with respect to geometrical axis " O ", and through the transition point (see figure 8) between top 13b and the sidepiece itself.

The opening width of angle " α " can be easily by the suitable adjustment distance ' ' d ' ' control (see figure 9) between the first overlay planes N and the meridian plane P.Therefore can obtain any required angle value " α " that forms by sidepiece 13a and can not influence the orientation of top 13b.

If wish that top 13b is to be obliquely installed with respect to a circumference bearing of trend, then annular brace 11 and/or overlay device can be positioned to when from one when becoming radially direction to look in conjunction with axis " O ", the first overlay planes N and meridian plane P suitably tilt.In these cases, because the biasing between overlay planes N and the meridian plane P, the top 13b of each section 13 is with respect to through one of each formation among two sagittal plane P ' of the transition point between top itself and each sidepiece 13a and the different angle in the inclination angle that is formed by sidepiece itself " α ".By the distance ' ' d ' ' between suitable adjusting overlay planes N and the meridian plane P, opening of the inclination angle of sidepiece 13a " α " can change as required, and can not make the orientation of top 13b stand any variation.

When the covering in the whole circumferential extension of section 13 in annular brace 11 of first series is finished, along with the step that applies of the first principal part 4a of the no ductile structural 4 of described annular forms carcass structure 2, wherein the first principal part 4a is applied on the zone near each inner rim of carcass bed course 3 (see figure 10)s of making, the carcass zone that is called " tyre bead " to obtain is used to guarantee tire is fixed to the installation wheel hub of a correspondence.

Each described first principal part 4a comprises the annular insert 21 of at least one the first circumferential no ductility, the insert fundamental form is as the coaxial tops of how much rotating shafts with annular brace 11, and is placed on the sidepiece 13a that leans against the banded section 13 that belongs to first series on the circumferential interior location.

The first annular insert 21 is preferably made by at least one long and thin metal spare that is wound in the coil 21a of several almost coaxials.Coil 21a can or be limited by a continuous helix, and perhaps the coaxial rings that is formed by each elongate articles limits.

First obturator 22 and first annular insert 21 combinations of making by elastomeric material, first obturator is preferably thermoplastic, have the hardness between 48 ° that measure under 23 ℃ the temperature-55 ° of Shore D, and preferably have a radially extension bigger than radially extending of the first annular insert 21.

According to a preferred version, the first annular insert 21 is formed directly on the sidepiece 13a of section 13, and can form coil by being wrapped on the wire part under rod or other act on the help of lip-deep appropriate device of annular brace 11.

Since the viscosity that covers the elastic layer 20 of the section 13 that belongs to first series and be placed on this lining 10 on one's body of drum before, the firm location that in the process that forms step, can guarantee each coil 21.

Subsequently, by for example apply one by near the elastomeric material of the extruder of drum 11 continuously band first obturator 22 can be formed directly into again on the first annular insert 21.Continuously band can have final from the cross-sectional configuration of first obturator 22 of each extruder.Perhaps, band can have with respect to the obturator small cross section continuously, and can be several to obtain obturator in side offside and/or the stacked coil that concerns setting, so that first obturator 22 is limited in its final configuration by band itself is applied to.

After applying the first principal part 4a of annular reinforcing structure 4, finish the formation of the first carcass bed course 3a by the section 14 that covers second series, become the section 14 that required size obtains second series by cutting continuous strap-like member 2a, and to be applied on the ring drums 11 with reference to the section 13 identical modes that belong to first series.

Clearly visible from Fig. 5-11, each section 14 that belongs to second series becomes U-shaped to place around the cross-sectional profiles of annular brace 11 between two that belong to first series continuous sections 13 and according to an orientation that is parallel to second series.In more detail, each section 14 that belongs to second series has each top 14b between the top 13b that circumferentially is stacked in the section 13 that belongs to first series, to fill the space " S " between it, and also have a pair of sidepiece 14a, on respect to the relative axial position of the end wing of the section that belongs to first series with the end wing of the stacked relation supporting cross section of each first principal part 4a of annular reinforcing structure 4 itself.

The sidepiece 13a part that belongs to the sidepiece 14a of each section 14 of second series and two continuous sections 13 that belong to first series in addition is overlapping, each section 13 all has radially outside and sidepiece itself and the top 13b at each principal part 4a, the extension between the transition region between the 14b.

Owing to the adjacent sidepiece 13a that radially locatees with respect to the geometrical axis of annular brace 11, mutual convergence between the 14a, belong to first series section 13 sidepiece 13a overlapping or to cover be that the circumferential amplitude of overlay region reduces gradually from one in the maximum of measuring near the radially outside of the first principal part 4a of each annular reinforcing structure 4, up to becoming at sidepiece 13a, 14a and top 13b, a null value of the transition region between the 14b.

After the covering of finishing the section 14 that belongs to second series in the above described manner, begin to form the second carcass bed course 3b by the section 15 that covers the 3rd series.

The section 15 that belongs to the 3rd series is also placed around the cross-sectional profiles of the first carcass bed course 3a with the U-shaped configuration, and circumferentially pitch equals its a plurality of width or equals the twice of described width at least, mode is basic and same or similar with reference to the described mode of covering that belongs to the first and second

serial sections

13,14.

Clearly visible in Figure 12, one belong in the scheme easily the 3rd series section 15 be placed among one the second overlay planes N ', this plane with respect to the meridian plane P from the first overlay planes N at the opposite side upper offset.

Like this, the top of the section 15 of the 3rd series with belong to first and/or the relation of the stacked on top of the

section

13,14 of second series be arranged in parallel.The sidepiece 15a of section 15 that belongs to the 3rd series is then with respect to the radially reference planes R ' angle of inclination " α " of the transition point between each sidepiece and each top 15b, its orientation is the sidepiece 13a with respect to the section that belongs to first and second series, 14a cross bearing.

On the end wing of the section 15 that carries out belonging to the 3rd series on the relative axial position with respect to the above-mentioned first principal part 4a, apply the second principal part 4b of annular reinforcing structure 4 then.

As seen, each second principal part preferably constitutes in the mode identical with the first principal part 4a from accompanying drawing.

Particularly, each second principal part 4b has the second annular insert 24 of a circumferential no ductility separately, insert 24 is formed by at least one elongate articles that is arranged among the coaxial coil 24a separately, so that form one with carcass structure 2 coaxial settings and near carcass bed course 3a, the top of the inner rim of 3b.

Second obturator 25 of being made by elastomeric material is arranged on the end wing of the

section

14,15 that belongs to the second and the 3rd series with the second annular insert 24, and its generation type is identical with first obturator 22.

The second annular insert 24 and second obturator 25 and the second principal part 4b make as a whole its and finish with applying and can carry out in the mode identical with the above-mentioned first principal part 4a.

Then by finish the formation of the second carcass bed course 3b at the section 16 of the middle covering Quaternary system row of the second overlay planes N ', the section 16 of each Quaternary system row is inserted between two sections 15 that belong to the 3rd series and is overlapping by its sidepiece 14a and the second principal part 4b, and the covering position is positioned at respectively on the relative axial position with respect to the sidepiece of the section 14 that belongs to the second and the 3rd series and 15.

According to a preferred embodiment of the present invention, after the section 16 that belongs to the Quaternary system row covers, finish the formation of annular reinforcing structure 4 at tyre bead.

For this reason, in Fig. 7 and 15, as seen,, on the end wing of the section 16 that belongs to the Quaternary system row, apply an other portion 26 for each annular reinforcing structure 4.

Best, each other portion 26 is made by at least one other crown annular insert substantially.This other annular insert 26 can for example be obtained by radially twining several coils that are arranged side by side at one, so independent elongate articles directly lean against on the second carcass bed course 3b that before had been formed on the annular brace 11, with the second annular insert 26 that forms and carcass bed course itself directly contacts.

After this operation, each sidepiece that belongs to the section 16 of Quaternary system row advantageously is enclosed between the other portion 26 of the second principal part 4b and independent annular reinforcing structure 4.

In radial, a common band structure 5 is applied on the carcass structure 2.

This band structure 5 can by for those skilled in the art easily any way make, and band structure comprises one first and one second belt 6a substantially in an example shown, 6b, belt have the rope of cross bearing respectively.An auxiliary belt 7 is stacked in belt 6a, and on the 6b, this auxiliary belt is for example by around belt 6a, and 6b twines at least one continuous rope and obtains, and rope is wound in axially be arranged side by side basic and is the coil of circumference.

A tread piece 8 is applied on the band structure 5 then, and sidewall 9 is applied on the sidepiece of carcass structure 2, and sidewall also can be obtained by any mode easily for those skilled in the art.

Can be advantageously used in that to finish tire 1 open in the european patent application No.97830632.2 of the embodiment of the formation on the annular brace 11 the applicant.

Like this tire 1 of Zhi Zaoing can from support 11 pass to one after taking off can be with any known and cure step that usual manner carries out.

The present invention has many significant advantage.

In the reality, the carcass structure that relates to can directly be obtained on an annular brace, can make whole tire easily on annular brace.Can avoid like this all with traditional manufacture process common with all problems semi-finished product manufacturing, storage and management.

With at file US 5,362, the method described in 343 is compared, the manufacturing time of carcass bed course can reduce greatly, because can cover each

section

13,14 or the

section

13,14 of being included in as much as possible simultaneously from the wire part among continuous band-shaped the 2a wherein.Utilize

section

13,14 needing also to avoid on annular brace 11, covering before lining 10.In fact, the elastic layer 18 that is used to form continuous band-shaped 2a itself can guarantee that described strap-like member is bonded on the annular brace 11 effectively, thereby guarantees fixedlying positioning of each

section

13,14.

Section

13,14 and be combined in the positioning accuracy of wire part wherein can be further by following true the improvement, promptly each section has an important property firm in structure, makes it can be to by the vibration of overlay device transmission or similarly to shake effect unaffected.This be should be noted that as U.S. Patent No. 5,362 covering of each rope described in 343 is owing to bear vibration and/or shake some problems that have at rope described in the covering step process.

In addition, according to the present invention, cover simultaneously a plurality of wire parts can so that when relate to when covering each rope overlay device than required with lower ratio operation, can further help operating accuracy like this and can not damage productivity ratio on the other hand.

In addition, on the annular brace of identical with the tire after a processing substantially profile, directly cover the inaccessiable density of known method that banded section can be obtained the usefulness prior art along top-direction, cover the carcass bed course of a cylindrical sleeve-shaped in the prior art, and form it into an annular shape subsequently, make the carcass bed course rope attenuation that is arranged on the tire top of finishing then.

In addition, each banded section can firmly be fastened on the annular brace by the vacuum effect that produces by suction pipe, by firm fastening can not being obtained by the known method of the covering of carrying out each rope of vacuum generation.

With reference to its carcass structure 2, the structure of tire of the present invention and structure can be obtained the significant improvement of performance and structural strength.

Particularly, covering elongated sections in respect to the plane of annular brace meridian plane bias can make the top of each section have the gradient different with sidepiece.

Can obtain a kind of tire like this, the wire part that wherein forms the carcass bed course has the radial location of distinguishing on the tire top, and has the location that intersects respectively in the inclination of sidewall wire part between a carcass bed course and another bed course.

Because distinguish the radial location of the wire part of carcass bed course on the top, the tire that is provided with such carcass structure has good longitudinal flexible characteristic (causing effectively absorbing the out-of-flatness of road) and steering stability.

The location that crosses one another of sidewall and bead region wire part then again especially for quickening and braking procedure in the distorting stress that produces and provide good structural strength at anti-skidding.

Especially very favourable for height and very high performance low profile tire in this respect, wherein the structural strength of sidewall represents that an important key factor is also because the high torque value that tire must be able to transmit.

Should also be noted that obtaining of the technology of the present invention effect is not to depend on by strap-like member to form the carcass bed course.In fact, the present invention also can be applied to its bed course by on the carcass structure that covers each rope and make.

It should still be noted that finishing of carcass structure can also relate to or form an independent carcass bed course, perhaps by respectively by being arranged on two carcass bed courses making with respect to the elongate articles of first and second series of a meridian plane in the bias plane on the opposed side edges respectively by the elongated sections that is arranged in the bias plane on the opposed side edges respectively of two series.

It should still be noted that, the feature that the architectural feature of the loop configuration 4 of no ductility and loop configuration are attached in the carcass bed course can further increase the structural strength of tire 1 in tyre bead and sidewall region, wherein usually needs the structural strength of the bigger effect that causes at slope thrust at this.

In fact, the wire part 17 of existence and the

section

13,14,15,16 that belongs to different series that closely is connected to the

annular insert

21,24,26 of the circumferential no ductility on carcass bed course 3a, the 3b forms good connection.Carcass structure 2 is further strengthened in the zone corresponding to tire 1 tyre bead like this, and do not need to use an other similar slip-knot around the banded insert that is called " side plate " that annular reinforcing structure 4 twines for this reason, seek help from " side plate " on the contrary in the prior art.

In fact the structure of annular reinforcing structure 4 can prevent that tyre bead is out of shape and rotate by leaning against its its indication head lamp brush guard pivot that is arranged on the base in the wheel rim separately under the influence of slope thrust.

Particularly, the existence that is noted that first insert 21, second insert 24 and the auxiliary insert 26 that directly contact with the end wing of section prevents tyre bead bending and the possibility of rotating effectively under the influence of slope thrust.

Under this viewpoint, the performance of annular reinforcing structure 4 is basic similar to disclosed ruggedized construction in the applicant's european patent application No.97830731.2, and this text at this as a reference.

Should also be noted that

annular insert

21,24,26 provides at tyre bead further protects tire.
